Application filed June 17,1905. Serial No. 265.731.

eflicient lubricator designed more especially for use on uprightpiston-rods and valvestems and adapted to be expeditiously applied toand removed from the same without the employment of skilled labor ortools.

The invention will be fully understood from the following descriptionand claims when taken in connection with the accompanying drawings,forming part of this specification, in which Figure 1 is an elevationillustrating the lubricator constituting the present and preferredembodiment of my invention in its proper position on a piston-rod. Fig.2 is a horizontal section taken in the plane indicated by the line 2 2of Fig. 1 looking downwardly. Fig. 3 is a horizontal section taken inthe plane indicated by the line 3 3 of Fig. 1; and Fig. 4 is a detailenlarged transverse section illustrating the relative arrangement of theband, the wick, the swab, and one of the oil-cups of the lubricator,together with the means whereby lubricant is supplied to the swab andthe wick from the cup.

Similar letters designate corresponding parts in all of the views of thedrawings, referring to which A is the band of the lubricator, which ispreferably a strip of brass or other sheet metal and is thereforepossessed of more or less resiliency, whereby its ends have a tend encyto spring apart, and B is the connection for the ends of the band. Thisconnection is preferably a loop pivoted to one end of the band andarranged to be swung into and out of engagement with a lip or keeper (.4on the other end.

C C are oil-cups, of which three are prefering transversely through thelower portion of the band, as clearly shown in Fig. i. The hollow arms wserve to [ixedly connect the oil-cups U to the band A, and by reason ofthe slits 1? it will be observed that the said hollow arms are incommunication with the cups throughout the height thereof, with theresult that a full supply of oil to the ports or d nets (2 at all timesis assured.

l) is a wick substantially corresponding in length to the band A andarranged at the inner side thereof, so as to receive lubricant from theducts or ports 1 and E is a swab, preferably of cord, wrapped around theband A and the wick l) and also around the hollow arms and having forits functions to apply lubricant to the pistonro .l or other piece ofmachinery bearing the lubricator and retain the excess supply oflubricant, so as to prevent waste thereof.

The lubricator is applied as shown in Figs. 1, 2. and 3 of thedrawings-that is to say, it is placed about the pistonrod, valve-stem,or other part to be lubricated and is fastened-in position by theengagement of the loop B with the lip u. \Vhen the lubricator is appliedas statcd, the band A will be placed under slight tension and the swabwill be pressed against the pistona'od, with the result that there is noliability of casual movement of the lubricator on the rod. It will alsobe noted that when the loopB is disengaged from the lip a the ends ofthe band A will spring apart, and the lubricatormay then be quickly andeasily removed from the rod.

Incident to the use of the lubricator oil is supplied at intervals tothe cups G, and it will be readily appreciated that such oil will passfrom the interiors of the cups through the slits (Z, the hollow arms 0,and the ducts w in the order named to the wick D, by which it will beabsorbed and from which it will be supplied to the swab E as needed. Theoflice of the swab is to apply the lubricant to the piston-rod or otherpart to be lubricated, and it will be noticed that the use of the saidswab in connection with the wick assures a plentiful supply of lubricantto the rod and yet precludes dripping and waste of the lubri' cant.

\Vhen the wick D and the swab E of my novel lubricator becomedeteriorated through use, they may obviously be readily removed andreplaced by a new wick and swab, so it will be seen that the majorportion of my improved device will last for an indelinite period. Itwill further be noticed that when the wick and the swab are removed, asabove suggested, the lubricator may be readily cleared of collectedsediment and otherwise thoroughly cleaned.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-

1. In a lubricator, the combination of means for holding the lubricatoron a rod, a wick carried by said means, means for supplying lubricant tothe wick also carried by the firstmentioned means, and a swabsurrounding the wick.

2. In a lubricator, the combination of means for holding the lubricatoron a rod, a wick carried by said means, a lubricant-holder also carriedby said. means and connected with a wick, and a swab surrounding thesaid means and the wick.

3. In a lubricator, the combination of a band provided with means forfastening it about a rod, one or more lubricant-cups carried by saidband, a swab surrounding the band, and one or more conduits intermediatethe cup or cups and the swab.

4. In a lubricator, the combination of a band provided with means forfastening it about a rod, one or more lubricant-cups carried by saidband, a wick arranged at the inner side of the band, one or moreconduits for carrying oil from the cup or cups to the wick,

and a swab surrounding the band and the wick.

5. In a lubricator, the combination of a band provided with means forfastening it about a rod and having a port or duct, an oilcup disposedat the outer side of the band, a hollow arm intermediate the band andthe cup and connecting the port or duct of the former and the interiorof the latter, and a swab surrounding the band and also surrounding thesaid hollow arm.

6. In a lubricator, the combination of a band provided with means forfastening it about a rodand having a port or duct, an oilcup disposed atthe outer side of the band, a hollow arm intermediate the band and thecup and connecting the port or duct of the former and the interior ofthe latter, a wick arranged at the inner side of the band, and a swabsurrounding the band and the wick and also surrounding the said hollowarm.

7. In a lubricator, the combination of a band, means for fastening saidband about a rod, absorbent material surrounding the band and alsosurrounding a wick interposed between it and the band, the said wick,and an oil-cup carried by the band and provided with means for supplyingthe wick and the absorbent material with lubricant.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
